I hope that General Electronics is a reasonable place for this query .... only other place would be off-topic but I think it is more on-topic than off-topic...
I am trying to design an event triggering algorithm for my recording accelerometer. I've been looking at airbag triggering because that seems like the only general application with similar behavior. Hope that someone here on the list has some first hand experience in this area. No, I am not talking about the kind of experience Torby had recently
Anyway, the questions, hoping that they are not too uninformed:
1. Is is purely acceleration or is there a rate of change of acceleration involved in the determination (to trigger the airbag)?
2. What sort of acceleration trigger levels are involved?
3. How does triggering deal with vehicle on a slope along the axis of motion? Is the trigger threshold simply so large compared to the gravity component projected onto that axis through tilt that gravity can just be ignored?
4. Any useful references on the subject?
